PCIe-BASEData Acquisition and Control Card (PCIe) Measurement & Control. Multifunctional. Stationary measurement data acquisition in latest "PCI Express" technology: The PCIe-BASE is a multifunctional data acquisition and control card. Its modular structure guarantees individual and flexible adjustment to a measuring task. Modular Concept. Optimize Price-Performance-Ratio. Perfectly adapted to the respective measurement application, data acquisition modules can be selected to equip the two module slots of the PCIe-BASE. It is the customer who decides about performance and price of his DAQ system! Modules: MADDA. MDA. MCAN. What Would you Like? A great variety of analog plug-on modules is available differing in the number of inputs and outputs, resolution and sampling rate. If a MADDA module e.g. is combined with a CAN module, analog measurements and via the CAN interface are possible. Analog, digital, and CAN channels are sampled time-synchronously. 32 Digital I/O. 3 Counters. The PCIe-BASE features 32 digital lines, which means that the base board is a digital I/O card itself. The direction of the two 16-bit ports is set via software. 3 counters accessible via any digital inputs allow the acquisition of counting pulses or the connection of incremental encoders. PCIe. Be on the Cutting Edge. Designed in "PCIe x1" format, the PCIe-BASE can be installed in any PCIe slot. In the long term, this extremely powerful interface will completely replace the predecessor "PCI" in the PC. Due to Plug&Play, the card is recognized automatically by the PC making installation a lot easier. Windows®. That's it. The PCIe-BASE can be used on Windows® XP/7/8/10. The entire software for installation and programming (ActiveX Control) of the multifunction card is included for free. NextView®4. Try for Free. The DAQ system is supported by NextView® 4, the software for data acquisition and analysis. A fully functional 30-day trial is included with delivery to directly test the functionality of the PCIe-BASE. bavarian measurement company munich

1 Module Concept 1.1 Overview The following PCB view shows the module slots Ml and M2, which can be assembled with analog data acquisition modules (MADDA series), analog control modules (MADDA/MDA series) or a CAN interface module (MCAN). They can be used in any combination.

1.2 Module Slots M1 and M2 D-Sub 37 Ml The channels of the module slot Ml are available at the 37-pin D-Sub connector as well as at the pin connectors Kl, K2. The connections of the second module slot M2 are accessible at the pin connectors K3, K4. With the optional accessory ZUKA16 (see chapter 5), the channels of the module slot M2 are lead out to an additional D-Sub 37 female connector (connect line 1 -colored - of ZUKA16 with pin 1 of the pin connector K3 - square pad - and attach 2. connector in parallel to K4). The figure below shows the pin assignment of the module slots M1 and M2...

• Channels of MCAN modules cannot be reached in that way at the D-Sub37 female connector! • The corresponding ground pin for the analog channels of the M2 module slot is exclusively available at pin 17 of the D-Sub 37. 1.3 Pin Assignments of the Module Slots The following table shows which pins are used to connect the analog or CAN channels. The channels of the module in slot M1 are accessible at the 37-pin D-Sub female of the DAQ card. The connections of the module in slot M2 can be led through with the add-on cable ZUKA16 to an additional 37-pin D-Sub female. MODULE SLOT M1 DATA...

2 Digital Channels The PCIe-BASE features two digital ports with 16 inputs or outputs each. The lines are bidirectional. The connections are designed as two 20-way pin connectors (male) on the board (see Figure 1, p.2). • Pin connector K6 => port A, line 1..16 • Pin connector K5 => port B, line 1..16 ZUKA16 (D-Sub 37) K6 © • The digital inputs and outputs are protected by serial resistors! • At PC start, port A is set to input, port B to output. • Digital inputs will always be read synchronously in time together with the analog inputs. • Make sure the digital outputs of the device do not...

2.2 5V Auxiliary Voltage The PCIe-BASE provides an auxiliary voltage (e.g. for sensor supply) at pin 17, 18 of the pin connector K5. The 5 V DC output (100mA) is protected by a fuse (multifuse). In case of overload, it is sufficient to interrupt the power supply (turn off PC or disconnect the consumer load). After app. 1 min., the multifuse will be regenerated. 2.3 Counter The PCIe-BASE features three 32-bit counters allowing the connection of incremental encoders. The counter inputs (A, B, and Reset) can be assigned to any digital lines of the two digital ports (configure by software). The...

3 Interfacing Examples In the following examples, the signal is always connected at port A, line 1 (pin 11). Before, however, the relating digital port must have been switched to input (see chapter 3.1) or output (see chapter 3.2). 3.1 Interfacing Examples for Digital Inputs The 3.9kQ pull-down resistor sets the input to low if no voltage is applied there. 3.1.1 Connecting an Optocoupler Optocouplers provide optimum protection at each input line. With them, it is possible to connect higher voltages and to protect the hardware from being destroyed. In this regard, please also see application...

3.1.4 Connecting a Counter / Incremental Encoder The connection of "Signal A", "Signal B" and "Reset" is possible at any digital line. O Make sure to configure the relating digital lines as input and to assign them to the counter. Serial resistors in the output lines limit the current and protect the hardware from being destroyed. 3.2.1 Connecting an LED Only so-called low-current LEDs can be used, because they already work with 1mA current. Please also observe the total current listed in the technical data (see chapter 7). Ausgang/ output 3.2.2 Connecting a Relay A connected relay is ideal...
